An interesting understandable exception to this rule might be if you have satellited your way into a very large tournament that you would never enter out of your own pocket. The WSOP for example. Although it still would not be the correct play to fold your way into the money if you were in a postion to do so (allowing your blinds to be stolen for the hour previous to the bubble for example), it is perhaps more understandable than doing so in a 30 dollar online MTT

. I witnessed a real life case of this on the last
ladbrokes poker cruise. A geordie lad had qualified for the whole shebang, cruse + 5k main event entry. He was so skint he had even tried to lose his online qualifer on the bubble. (The bubble had paid 2k cash whilst the next place up was cruise + main event worth 11k). Going all in with crap every hand on the bubble he told me, he got called constantly and just sucked out on everyone

. Anyway he found himself on the bubble of the main event with a small stack. Next out got 0 whilst the person after him got something between 5 and 6 grand, I cant quite remember the exact amount. Anyway someone raised before him and he looked down at AA. He was so short as to obviously be called if he went in and he decided to chicken out and fold, clearly giving up ANY chance he ever had of winning the whole thing and the huge first prize to guarantee a few grand. He made it into the money and was out very quickly after.
Clearly this was "wrong" in the poker sense but what would you have all done in this spot? (honest answers please lol). I would have 100% moved all in.
